I vacuumed the pre-filter one month after purchase but there is a red light blinking on top saying to change it. How do I reset it??

Look for a Reset button near the red light. Press the button and hold for five seconds or so; the light will turn off (or it will when you release the Reset button).

You must hold in the reset button till the light goes off. If it doesn't go off after 10 seconds, I've found that I sometimes have to try again.

If you have already tried resetting, then I believe there is nothing to be done except get a new one. Brita did have a toll free number to call if this happened. I think the number is on the instructions. Instructions may only come with new tap mount (not sure if they are in the new filter only package). I had to get a entire new unit after about 5 years usage on 1st one I had. Hope you are successful with resetting! Good luck.

It's probably a dirty filter. You can wash and dry them or buy a new ones for about $12 each (pre-canister and HEPA). Made a world of difference when I cleaned mine--wondered why it ran like doo-doo after 10 years since they're supposed to never lose suction. Apparently they aren't miracle machines--you do need to clean/replace the filters occasionally.

The only site I ever found was zane.com I was on my cell so there was limited information. I have to go back myself to look for a new filter. Good luck! I hope you find it because it is a really good little machine. If not, I would go to the big box store and look in the vacuum section. Thanks!

We had the same problem - evidently we may have waited too long to change the filter and so much pressure built up in the chamber that it ruined the plastic threads in the cap. We had to use some large channel lock pliers to turn the cap out and ruined the threads in the process. We contacted customer support about the problem and they replaced the unit - hope this helps

I recently washed the post filter and the samething happened. The suggestion regarding blowing out the filter with an air compressor worked perfectly. Its been a month now and the filter stays in place. I believe the washing of the filter (even when the directions are followed) caused the dust/dirt to harden over the pores so the positive pressure just blows out the filter. If you don't have a air compressor, try those computer dust cleaner or wash the filter more aggressively than what the dyson instructions suggest.

Vacuuming the filter and resetting the filter worked for me, at least temporarily. Still disappointed in Sanyo though.

Hello. You just need to hold down the filter button until it resets. That should work!

Happened to me. I removed and reinserted the filter a dozen times. No luck. Ended up returning it. I recommend the Pur brand.

According to the booklet, when to replace the HEPA filter depends on hours used, air quality, and location of the unit. In most cases the unit will need to be replaced annually, and it should be changed after the 'change filter' light comes on. For best performance change the carbon pre-filter every 3 months. It warns specifically: "Caution, do not wash and reuse the true HEPA filter or the carbon pre-filter as they will not work effectively." Having said that, I have vacuumed the carbon pre-filter with a vacuum cleaner attachment since it collects a huge amount of dust. I haven't needed to change the HEPA yet.

What I did was vacuum the actual blue filter thoroughly as it really didn't look very dirty even though I got a "change filter" message. Then I washed the plastic grid piece it fits into thoroughly and let it dry. I reassembled it and still got a change filter message. However, I discovered there is a tiny "reset filter" hole near the top of the inside of the unit where you place the filter. I stuck a paperclip in the hole and pushed, and now it's behaving as if it has a brand new filter! I think maybe if this is done on a regular basis that you can get a lot more use out of this unit, even though the filters are "no longer available."

Hi! I recently experienced a similar problem! I had removed all the filters (there are three removable ones - two foam and one white paper), washed them all, cleaned everything off the beater bar/roller, shook out the tube/hose, even unscrewed the bottom and cleaned out whatever I could find there too! Still, as soon as I turned it on, it was going to red! Grrrrrr I FINALLY found the problem. You might have already checked this, but just in case, sharing it here. It might help you or someone else. When looking at back of the vacuum, on the right side, BEHIND the main tube/hose, you can see the tube attach to the black vacuum base which feeds into the clear body where the dirt goes in. I could not see any clogs anywhere. BUT - this part of the tube/hose COMES OFF - it is easy to overlook, but it twists and releases. I did that as a last resort, and found my problem! There was a piece of paper in there, and all kinds of dirt and hair (we all shed some and have two cats) were packed pretty solid behind the paper! It took a tool like a crochet hook to get it all out and unpacked! (I have a metal "tube turner" for sewing, which is what I used, but anything super thin and long can work, as long as you do not go THROUGH the hose.) I took an amazing amount of junk that had not come out when shaking the hose, cleaning things, even taking the rest of the vacuum apart... it hides in that last curve of the hose! I hope this helps someone else, because this is a great little powerhouse of the vacuum that is perfect for our little townhouse. But the clogging does happen sometimes, and I've now found the FIRST place I'll look, instead of the dead last! ;-)

It clogged mine up, but nothing I couldn't clean the filter on. I would suggest use a shop vac at first and then go over with your good vacuum.

This is the manufacturer's recommendation: "Before operating the air purifier, record the date of installation on the HEPA filter. Under normal conditions, the HEPA filter should be replaced annually, and the pre-filter should be replaced every 3 months." That is directly from the manual. I have had my air purifier for about 6 months and have only changed the pre-filter once. I vacuum if off about every 2 weeks. Your situation might be different depending on how must dust is being filtered.

Did you double check that the new filters are properly in place? I would take them out and put them in again. Otherwise, call the customer service number for assistance at 1-800-541-6645. I hope this helps.
